Question 55218: I used your solver for finding the equation of straight line given 2 points I entered these 2 points (7,3) and (9, -2). The answer that came back shows the slope to be -2.5 But when I do y2-y1 and x2-x1 I get -5/2 so what did I do wrong. This is a problem on my homework and I would appreciate your input. Thanks, D Steele

You can put this solution on YOUR website!
-2.5 = -5/2
They are the same.
